To all whom it may concern:

Be it known that I, FRED R. IuAUs, a citizen of the United States, residing at leveland in the county of Cuyahogaand State of Ohio, have invented a certain new and useful Improvement in Rim-Connecting- Hooks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a bridge-plate for connectingthe abutting ends of a transplit demountable tire carrying rim, and has for its object to provide a bridge-plate which may be more easily and cheaply manufactured and yet which is strong and more efficient than the ones heretofore in use.

' More particularly, this invention relates to one of the commercial types of bridgeplates which comprises a body member having hook at one end of the bridge-plate to engage one end of a transplit rim and having two or more rivets on the otherend of the bridge-plate to engage the other end of the rim, and having a driving lug.

The present method of manufacturing these bridge-plates is to take a fiat bar or plate having the proper cross section to form the bridge-plate and trimming it to the correct size. It is then counter-bored to receive the driving lug and the rim-com necting rivets which must be separately made and inserted and then riveted over.

As the cross-sectional area of the aperture which receives the driving lug is equal {to substantially half, or slightly greater than half of the cross-sectional area of the bridge-plate, the latter is greatly weakened by the presence of such aperture, even though the aperture be filled by a separate member as a driving lug, the head of which is substantially riveted over.

'According to my invention, I eliminate the waste of material consequent to making these parts each separately from blanks by heating a bar of steel and shaping it in any suitable manner, as by drop-forging, so that the bridge-plate, driving lug and rivets are all formed integral in one opera-- tion. Furthermore, I have found it prac tical to make two or more of these bridge plates simultaneously, that is, to use dies which will form two or more bridge-plates at the same time.

In the drawings forming a part of this specification, Fig. 1 shows a. plan view of two came adjacent the hook of the other.

ous fin 4 projects from the sides of the bridge-plates, due to the excess of metal in one original piece, as is customary in dropforging. The bridge-plate comprises a body member having a hook 5 at one end, and on the same side at the other end two or more rivets 6. On the opposite side of the plate is a driving-lug! 7. The hook 5 engages '1 slot at one end of the rim (not shown). and the rivets 6 engage the rivet holes in the other end of the rim. The hook 5 may be detached from this slot to permit collapsing of the rim, in order to facilitate placing the tire on, or removing it from the rim.

On the same side of the plate member as the hook and rivets is the beveled or unnercut portion 8 designed to permit the insertion of a tool to withdraw the hook of the plate to collapse the rim in order to remove the tire.

The driving luo; 7 engages an apertur in the felloe band of the wheel to prevent relative movement between the wheel and the rim when the wheel is driven.

In order to accomplish the proper dis placement of metal to form these bridgeplates so that the hook and rivets will be on one side and the driving-lug on the other, I have found it advisable to make the dies of such shape as to compensate for the displacement. I find that if the dies are made so that the fin formed on the edges of the bridge-plates lies obliquely to these edges, as shown in Fig. 2, the metal on each sideof this division line is about equal. When the two-bridge plates are formed at the same time, they are preferably placed so that the riveted ends are adjacent in order that the whole line of contact between the dies may have a more uniform curve throughout the center than would be the case if the plates were placed so that the riveted ends of one fter the bridge-plates are formed as shown in Fig. l, the fin is sheared from them and they are ready to be plated, if desired, be: fore being applied to the rim.

It will thus be seen that I am able to make a rim connecting bridge-plate which has far greater strength than the ones heretofore used, and which can be easily and cheaply manufactured.

Having thus described my invention what I claim is 2- As a new article of manufacture, a forged rivets projecting from the opposite face thereof, the hook portion extending across oneend of the plate and the rivets positioned at and near the opposite end.

In testlmony whereof, I hereunto V afiix my signature.

FRED R. KLAUS.
